Abstract

A three-dimensional finite element model is used in order to evaluate the tensile and bending rigidities and, subsequently, Young’s modulus of non-chiral and chiral single-walled carbon nanotubes containing vacancy defects. It is shown that the Young’s modulus of single-walled carbon nanotubes with vacancies is sensitive to the presence of vacancy defects in nanotube: it decreases with increasing of the density of vacancy defects.
